Did the Library of Alexandria really burn down in one great fire?

The ancient world's greatest library didn't go up in one blaze. It faded away over centuries.

▶ Start the story

Probably not. The popular picture is a single catastrophe, one night of flames in which all ancient knowledge vanished. Historians describe something slower and sadder: the Library's influence declined gradually over several centuries, through purges, neglect and war, until there was nothing left to burn.

The Library was one of the largest of the ancient world, though estimates of its size range wildly, from 40,000 to 700,000 scrolls. Its decline began in 145 BC, when King Ptolemy VIII purged Alexandria's intellectuals and the head librarian fled into exile.

Julius Caesar did start a fire in 48 BC, and it burned part of the Library or its collection. But it is unclear how much was lost, and the Library seems to have survived or been rebuilt soon after. Some scholars think the flames hit warehouses near the docks rather than the Library itself.

Under Roman rule the Library dwindled from lack of money and support, and its membership seems to have ended by the 260s AD. In 272 AD, fighting destroyed the quarter where it stood. Its daughter collection in the Serapeum temple was demolished in 391. And the famous story that an Arab caliph ordered the books burned in 642? It first appeared 500 years after the event, when the Library was likely long gone.

The Library wasn't killed in a night. It was starved over centuries.
